Scale ratio simply means the ratio that makes quantities to be in proportion.
The objects and scales are:
- A person:- 1 in : 1ft
- A football field:- 1: 1000
- The state of Washington:- 1: 10,000,000
- The floor plan of a house:- 1 cm : 1 m
- A rectangle farm: 1 : 100,000
To determine the scale ratio of the object, we simply make use of the closest dimension that represents the object
Person
In all the given scale, a person's height is most appropriately in inches and feet.
So, the scale ratio would be 1 in : 1ft
Football field
The dimension of the field is given as: 120 yard by 53 1/3 yards.
Because the length and width of the field are given (and they make use of the same unit), the scale ratio must be unit-less
The unit-less scale ratios are 1:1000, 1:100000 and 1:10000000
Of all these, 1:1000 is the most appropriate, because it is the smallest, and a football field is smaller than the state of Washington and a rectangular farm.
State of Washington
The dimension of the state is given as: 240 miles by 360 miles
Using the same illustration as the football field, the scale ratio must be unit-less
The remaining unit-less scale ratios are 1:100000 and 1:10000000
Of these two, 1:10,000,000 is the most appropriate, the state of Washington is bigger than a rectangular farm.
This also means that, the scale ratio of the rectangular farm would be 1:100,000
Floor plan of a house
In all the given scale, the floor plan is most appropriately in centimeters and meters.
So, the scale ratio would be 1 cm : 1 m
